?  In Tamilnadu so far 11 sites have
been identified for biomedical waste disposal.

?  6 units under operation are

       Kancheepuram(2)

       Vellore (1)

       Thanjavur (1)

       Ramanathapuram (1)

       Nilagiri (1)

?  Five units  under establishment are

       Coimbatore (2)

       Salem (1)

       Viruthunagar (1)

       Thirunelveli (1)

?  Packaging and labelling of
biomedical wastes

?  Transport

?  Different types  of wastes(according to WHO) :

?     Infectious : 
materials containing pathogens in sufficient  concentration or quantities can cause
disease.

?     Pathological: tissues, organs, body parts, body fluids,
chemicals, etc.

?     Radioactive: radiactive isotopes used in research.

?  Chemical process:

      Use of chemicals that act as disinfectant

       Sodium hypochlorite, peracetic acid, dry
inorganic chemicals, ozone,etc.

?  Thermal process:

    low heat system(93-177*C) – autoclave and
microwave

    high heat system(540-8300*C) –
incineration.

?  Mechanical process:

      compaction – reducing the volume of waste.

       Shredding – destroy plastic and paper
waste to prevent reuse after disinfection of wastes.

?  Irradiation :

      use of ionizing or ultraviolet radiation
in closed chamber.

      These system require post shredding to
recognize the waste unrecognizable.

 

?  Biological process:

        Use of biological enzymes for treating
biowastes.

       Decontamination of waste and
destructionof all organic constituents.

?  Deep burial:

       disposal of organic material after
disinfection.

?  Caustic tissue digestion:

         Decontamination with KoH.

         large stainless steel heated to 177*C
and pressurized to 55psi causes degradation of proteins into peptides, also
destroys any bacterial, viral, prion contaminant.

ü   even the bedding material has to be disinfected before
disposal.
